Human persons exist longer than a single moment in time; they persist through time. However, so far it has not been possible to make this natural and widespread assumption metaphysically comprehensible. The philosophical debate on personal identity is rather stuck in a dilemma: reductionist theories explain personal identity away, while non-reductionist theories fail to give any informative account at all. This chapter argues that this dilemma emerges from an underlying commitment, shared by both sides of in the debate, to an (...) ontology which that gives the priority to static unchanging things. The claim defended here is that the dilemma of personal identity can be overcome if we acknowledge the biological nature of human persons and switch to a process- ontological framework that takes process and change to be ontologically primary. Human persons are biological higher-order processes, rather than things, and their identity conditions can be scientifically investigated. (shrink)

This paper aims to motivate a new beginning in metaphysical thinking about persistence by drawing attention to the disappearance of change in current accounts of persistence. I defend the claim that the debate is stuck in a dilemma which results from neglecting the constructive role of change for persistence. Neither of the two main competing views, perdurantism and endurantism, captures the idea of persistence as an identity through time. I identify the fundamental ontological reasons for this, namely the shared commitment (...) to what I call ‘thing ontology’: an ontology that gives the ontological priority to static things. I conclude by briefly indicating how switching to a process ontological framework that takes process and change to be ontologically primary may allow for overcoming the dilemma of persistence.

What are persons and how do they exist? The predominant answer to this question in Western metaphysics is that persons, human and others, are, and exist as, substances, i.e., ontologically independent, well-demarcated things defined by an immutable (usually mental) essence. Change, on this view, is not essential for a person's identity; it is in fact more likely to be detrimental to it. In this chapter I want to suggest an alternative view of human persons which is motivated by an appreciation (...) of their biological nature. Organisms, human and non-human, are dynamical systems that for their existence and persistence depend on an ongoing interaction with the environment in which they are embedded. Taking seriously this most fundamental human condition leads to recognising human persons as processes, i.e., as entities for the identity of which change is essential. It also implies a holistic view of the human mind. (shrink)

In recent years, an increasing number of theoretical biologists and philosophers of biology have been opposing reductionist research agendas by appealing to the concept of biological autonomy which draws on the older concept of autopoiesis. In my paper, I investigate some of the ontological implications of this approach. The emphasis on autonomy and autopoiesis, together with the associated idea of organisational closure, might evoke the impression that organisms are to be categorised ontologically as substances: ontologically independent, well-individuated, discrete particulars. However, (...) I argue that this is mistaken. Autopoiesis and biological autonomy, properly understood, require a rigorous commitment to a process ontological view of life. (shrink)

In this monograph, I systematically analyse the debate in recent analytic metaphysics, with a special focus on recent biologically inspired (so-called animalist) theories of personal identity. I argue that the debate is stuck in a dilemma which is neither harmless nor new: the modern antagonism between the reductionist elimination of personal identity on the one hand and its non-reductionist mystification on the other rather repeats the antagonism between rationalist dogmatism and empirical scepticism in the 18th century’s debates on the soul. (...) This latter antagonism has been extensively examined by Kant who also sought for ways to overcome the dilemma. The systematic analysis of the modern ‘analytic’ debate is therefore followed by a presentation and critical discussion of the constructive approaches taken by Kant and post-Kantian ‘continental’ philosophers. From a Kantian perspective, what we are confronted with is a fundamental dialectic, originating in the very structure of human reason and threatening to turn metaphysics altogether into an arena of fruitless battles. The possibility of a satisfactory metaphysical account of transtemporal personal identity reveals itself to be contingent on the possibility of a ‘good’ metaphysics able to overcome that dialectic.

Within the philosophy of biology, recently promising steps have been made towards a biologically grounded concept of agency. Agency is described as bio-agency: the intrinsically normative adaptive behaviour of human and non-human organisms, arising from their biological autonomy. My paper assesses the bio-agency approach by examining criticism recently directed by its proponents against the project of embodied robotics. Defenders of the bio-agency approach have claimed that embodied robots do not, and for fundamental reasons cannot, qualify as artificial agents because they (...) do not fully realise biological autonomy. More particularly, it has been claimed that embodied robots fail to be agents because agency essentially requires metabolism. I shall argue that this criticism, while being valuable in bringing to the fore important differences between bio-agents and existing embodied robots, nevertheless is too strong. It relies on inferences from agency-as-we-know-it to agency-as-it-could-be which are justified neither empirically nor conceptually. (shrink)

This collection of essays, featuring a line-up of leading international scholars, argues that most work on cosmopolitanism uses a normative model, rather than fully interrogating the issue empirically, comparatively and globally.

According to dispositional realism, or dispositionalism, the entities inhabiting our world possess irreducibly dispositional properties – often called ‘powers’ – by means of which they are sources of change. Dispositionalism has become increasingly popular among metaphysicians in the last three decades as it offers a realist account of causation and provides novel avenues for understanding modality, laws of nature, agency, free will and other key concepts in metaphysics. At the same time, it is receiving growing interest among philosophers of science. (...) This reflects the substantial role scientific findings play in arguments for dispositionalism which, as a metaphysics of science, aims to unveil the very foundations of science. The present collection of essays brings together both strands of interest. It elucidates the ontological profile of dispositionalism by exploring its ontological commitments, and it discusses these from the perspective of the philosophy of science. The essays are written by both proponents of dispositionalism and sceptics so as to initiate an open-minded, constructive dialogue. (shrink)

For the most part, current reflections on the social seem to overemphasize either homogeneity or heterogeneity. Against this, here the argument is put forward that it is appropriate to think of the social as consisting of aspects of homogeneity or shared frames of reference and aspects of heterogeneity at the same time. This thought is developed particularly in contrast to normative concepts such as Bauman's sociality—republicanism nexus or Beck and Grande's ideas on European cosmopolitanism. With the help of concepts such (...) as sociation, glocalization and conflict, a basis will be developed for the elaboration of particular socials as a general social theory. This avoids falling into normative traps, which are usually risky when starting out from a historical particularity to explain current and future structures and features of notions such as European society.

In his famous essay „Der Essay als Form“ („The Essay as Form"), Adorno accuses Descartes of committing science to the ideal of absolute certainty (“zweifelsfreie Gewissheit”), thereby preluding the modern organized science (“organisierte Wissenschaft”), which in Adorno’s view has become alienated from real intellectual experience (“geistige Erfahrung”). In my essay, I criticize Adorno’s critique, showing that what Descartes in fact thinks about task and method of science comes much closer to the programmatical essayism of Critical Theory than Adorno supposed.

Can mental causation be naturalised without being eliminated? Thomas Buchheim argues that it can, proposing a neo-Aristotelian account dubbed "Horizontal Dualism". In this paper I assess this proposal. This article is part of a series of articles commenting on Thomas Buchheim's target article "Neuronenfeuer und seelische Tat. Ein neoaristotelischer Vorschlag zum Verständnis mentaler Kausalität", published in Philosophisches Jahrbuch 119,2 (2012), 332-346. The article was reprinted in: Mentale Verursachung [Mental Causation], ed. by Wilhelm Vossenkuhl, (Jahrbuch-Kontroversen 1), Freiburg: Alber, 2014.

In destructing traditional metaphysics, Heidegger accuses German Idealism of eliminating the finite in favour of the infinite. Particularly Hegel is criticized for ignoring the true finitude of Dasein and thereby misinterpreting being as infinite absolute. The paper explores this criticism in three steps. First, the main features of Heidegger’s early metaphysics of finite Dasein as developed in Being and Time will be traced, followed, second, by an examination of Heidegger’s claim that Hegel’s absolute has a temporal-finite origin. Taking a closer (...) look at Heidegger’s alternative, true finitude, leads finally to a reflection on some difficulties in Heidegger’s critique of Hegel. (shrink)

Do human embryos have a disposition to personhood? This has been argued within recent attempts to reformulate the classical argument from potentiality for the protection of human embryos with the help of the concept of disposition. In this paper, I analyse the central ontological premise of this new approach and show that any hopes of rehabilitating in dispositionalist terms the idea of a potential to personhood inherent in human embryos are mistaken. The dispositionalist version of the potentiality argument navigates in (...) same metaphysical waters as its predecessor and, hence, collides just the same with biological facts concerning human embryogenesis.

Eric Olson distinguishes his animalistic account of transtemporal personal identity from the apparently similar Bodily Criterion, among other things, by accusing the latter of being contaminated with Cartesian implications owing to its usage of the term ‚body‘. In contrast, Olson argues, Animalism is able to avoid these implications by substituting the concept of body for the concept of organism, which makes Animalism not only a distinct position, but also the better alternative to the Bodily Criterion. The paper critically reconstructs Olson’s (...) charge of Cartesianism against the Bodily Criterion, thereby differentiating between several variants of it. This eventually adds up to an evaluation of how suitable these criticisms are for defending Animalism at the expense of the Bodily Criterion. (shrink)

Recent decades have seen an increasing tendency to exclude the phenomenon of personality from the metaphysical investigation of personal identity. We are advised not to confuse personal identity as a philosophical subject, namely as the metaphysical issue of specifying what it is that makes a person staying numerically self-identical over time, with the psychological question of 'personal identity' which asks what makes someone the individual person they are with their particular character and history. However, one might be unsatisfied with this. (...) If (as common sense takes for granted) persons are to be conceived as beings possessing a personality, should there not be some more than superficial connection between personality and personal identity in the philosophical sense? This paper investigates this question by revealing the guiding - metaphysical assumptions behind the claim that personality and personal identity must be treated separately as well as by presenting the metaphysical alternative brushed aside by the adherents of this claim. In fact, I argue, there are two opposing views of the relation between personality and personal identity, these being grounded in two opposing metaphysical models of what a person is: the substance model and the bundle model of the person. However, it turns out that ultimately both competing models fail for fundamental reasons, which raises the question of what a way out of the dilemma might look like. (shrink)

Stephen Mumford has argued that dispositionalists ought to be endurantists because perdurantism, by breaking down persisting objects in sequences of static discrete existents, is at odds with a powers metaphysics. This has been contested by Neil Williams who offers his own version of ‘powerful’ perdurance where powers function as links between the temporal parts of persisting objects. Weighing up the arguments given by both sides, I show that the profile of ‘powerful’ persistence crucially depends on how one conceptualises the processes (...) involved in the manifestation of powers. As this turns out not to be determined per se by subscribing to some view labelled ‘powers view’, further discussion is needed as to what processes are and to what kind of process theory a powers metaphysics should commit itself in order to be convincing. I defend the claim that dispositionalism is best combined with a version of process ontology that is indeed incompatible with a perdurantist analysis of persistence. However, I argue that this does not imply that dispositionalists ought to be endurantists. (shrink)

The argument from potentiality for embryo protection relies on the assumption of a specific developmental potential of human embryos: as human embryos under normal conditions naturally developing into beings whose strong moral status is uncontroversial, namely into human persons, they likewise enjoy strong moral status. In my paper, I endeavour to spell out the ontological foundations of the argument from potentiality and to discuss them critically in the light of new empirical findings in embryology. Particular attention is hereby paid to (...) recent attempts to analyse the relevant notion of potentiality in terms of dispositions possessed by human embryos. I argue that, putting aside inappropriate essentialist speculations, there is no straightforward disposition of an embryo to become a person; such a disposition, if any, being rather successively generated in a multi-factored, highly context-sensitive process of biological development.

What are persons? There are two traditional answers: the relation model of person according to which a person is nothing more than a function of her relationships to other persons and the substance model which construes the person as persisting independently of relations and accidental properties. In my paper, I explore two interesting intersections of these models occurring in Augustine's speculative doctrine of trinity and in Heidegger’s early Theory of Dasein. Are Augustine’s and Heidegger’s conceptions of person convincing reconciliations of (...) the relation model and the substance model of person and how do they compare to each other? (shrink)

What is metaphysics? And what do we need it for? In this paper I argue that if we answer the first question appropriately, the second question becomes pointless. To understand what metaphysics is means to understand what it is for. I shall propose that metaphysics, as a philosophical discipline, is the addressing of reality with respect to the intelligibility of reality as a whole and, i.e., the addressing of reality's being-addressed in various contexts (everyday and scientific). Insofar as reason is (...) that which performs this ubiquitous addressing of reality, metaphysics – the addressing of the addressing of reality – turns out to be a self-addressal of reason. I shall rebut sceptical objections to this proposal, which are nourished by realist convictions, by emphasising an interesting and constructive metaphysical thesis entailed in the proposed understanding of metaphysics. At the same time, I shall oppose to idealist simplifications of the proposal by means of some reflections on the only legitimate source of a general (as opposed to special) critique of metaphysics: the questionability of the belief in a perfect intelligibility of reality.

The theological formulation of the “eternal manifestation of the Spirit through the Son”, developed by the patriarch of Constantinople Gregory of Cyprus in the 13th century, has been the subject of numerous studies in the 20th century and played an important role in the renewal of Trinitarian Orthodox theology. The interpretations are however diverging. Most theologians see in this formulation the manifestation of the uncreated energy, which would have been formalized later by Gregory Palamas. Others understand it as a hypostatic (...) reality concerning the third Person of the Trinity. This paper contributes to the discussion by re-analyzing the main texts of Gregory of Cyprus and of Gregory Palamas on this matter. In a first step, we defend the thesis that in the thought of the Byzantine patriarch, this expression truly concerns the hypostasis of the Spirit. In a second step, we question the existence of the theme of an “eternal manifestation” of the uncreated energy in the work of Gregory Palamas. (shrink)
